Position encoding using impedance comparison

An encoder system includes an encoding medium having a plurality of encoder target portions alternating with a plurality of encoder window portions. A sensor is movable in relation to the encoding medium. A signal source provides an electronic drive signal to the sensor and sensor electronics couple...

Zusammenfassung:An encoder system includes an encoding medium having a plurality of encoder target portions alternating with a plurality of encoder window portions. A sensor is movable in relation to the encoding medium. A signal source provides an electronic drive signal to the sensor and sensor electronics coupled to the sensor sense an electrical characteristic of the code strip to determine whether the sensor is next to an encoder target portion or is next to an encoder window portion.
